Well, don't know any particular places in Grants Pass, but i can give you a few hints.....I've got a hawk shell on my dodge full sized....I often will stay in state parks in OR and WA as some are open all year. Usually, though, they close the basic tent sites and only have the hookup or RV sites open. Kinda sucks as they cost a few more bucks. BUT they do have power and a small ceramic heater really keeps me toasty without having to run the little buddy heater. I would check online for the info on the parks you are going to pass on the road. You would be surprised how many of these parks are actually quite busy.
My last two trips I was going to go off the forest service roads and find a spot.....but it was hunting season and man there were a LOT of hunters out. I didn't want to take a chance and have someone use me or the camper for target practice......I found it more comforting to be around others....
As for Vancouver, a lot of the BC parks are closed. They have hunting season, too. Be careful. If you stay in the city, it is nice to have a small heater and extension cord so you can plug into a friends AC and not run the heater....
good luck.
